Hello kopusmellini I know exactly how you feel I used to have the same attitude and didnt want anything to do with social media but now I dont look at it as making friends but as making contacts. To put it in perspective look at it this way, if a multinational company has a facebook, twitter, or any other social media platform they are not out to make friends but to make contacts. They hope to offer the contact a service that will benifit both them and the "contact"
For suggestions to begin with I would suggest posting your song on Steemit and posting a page or 2 of your book here also.
I hope this helps you
